Dynamics Modeling & Simulation

Dynamics Modeling & Simulation

This option uses a Multiple Input Multiple Output (MIMO) dynamics model to calculate Inputs, Outputs, and Transfer functions.  Each part of the model can be calculated from the other two.   Transfer functions can be calculated from multiple Input and Output time waveforms.  Time domain windowing (Rectangular, Hanning, or Flat Top), linear or peak hold spectrum averaging, triggering, and overlap processing can be applied during Transfer function calculations.  Ordinary Coherences are also calculated for single Inputs, and Multiple & Partial Coherences are calculated for multiple Inputs.   Multiple Output time waveforms or frequency spectra can be calculated from Transfer functions and multiple Input time waveforms or frequency spectra, and animated ODS’s can be displayed directly from the Outputs.  Transfer functions can be derived from experiment or from mode shapes.  Inputs can be derived from experiment or synthesized.   Similarly, multiple Input time waveforms or frequency spectra can be calculated from Transfer functions and multiple Output time waveforms or frequency spectra.  The Outputs can be derived from experiment or synthesized.  This capability can be used for Force Path Analysis.
